yApplication :filed December rllhe device forming. the subject matter of this application is a road drag. It is desirablethat the transverse drag bars. have their ends set at different distances with respect to a central plane parallel or coincid ing with the dra'tt-.-line,"and this invention,

llt is `Within the province of the disclosure to improve generallj 2nd to enhance the utility oit devices oi' that type to which the invenf tion appertains. n

`With the above and other objects in vieiv which will appear as the description prt ceeds, the invention resides in the combina-y tion and arrangement of parts and .in the details ot construction hereinafter. describedV and claimed, it being understood that changes in the precise embodiment oi the inventicn herein disclosed? may be made Within the scope oi what is claimed7 .Without departing from the spirit ot the invention..`

ln the drawings y n Figure 1 shows in top plan7 a device constructcd in accordance with the invention, parts being in section;

Figure 2 is a section in a plane `parallel to the dratt line, parts remaining in elevation;

Figure 3 is a fragment-al cross section showing the mounting of the adjusting screw;

lFigure l is a sectional view showing part ol one ot the posts and the mounting of the nut into Which the adjusting screw is threaded.

The machine includes a rear drag member 17 an intermediate drag member 24 anda front drag member 3., each made up oi' a channel bar et to which a depending` blade is secured. The ends of the-drag members 1, 2 and 3 are arranged in approximately parallel lines A--B that are acutely disposed with respect to the draft line C-D. Upstanding i'irst posts 6 are secured to the ends of the drag members 17 2 and 3, and upstanding second posts 7 are secured to the drag members 1 and 3, an opstanding second post 8 is se cured to the intermediate drag member 2A The second pest 3V of the intermediate drag member 2 is located midway between the ends earner orifice.

drawings. ln. that figure, it appears, more overa that the long parts of the drag me1nr kbers 1an; L 3 are located at diagonally opposite corners of the machine, the short parts et the drag members 1 and 3 being located yat the other two diagonally opposite corners oi" the machine.

Outer tie bars 9 vare pivoted at 10 to the lirst posts Gand follow approximately the aforesaid acutely `disposed linesA-B. An intermedate tie bar 11 is disposed at right angles tothe drag members' 17 2, and?) and is pivcted ali-"1Q to the secondposts 7 and 8. X-shaped braces are provided7 andy include arms 15` pivoted atl 16 to.thegintermediate drag member 2 to the reardrag member 1, and to the'tront drag member 3Q The .arms ol each brace 14 that are pivoted to the short `parts ofthe iront drag member 3 and of the lrear draginember 1 yare spaced apart less Widely than. are the arms of each brace that are pivoted to they long parts of thetrent and rear drag members. ,Owing to this 'construction of the X-shaped braces `1&1 and to the specific arrangement Aof the braces with respect to the tie barsvll and 9, a .stronger and .more satisfactory'structure results than has been disclosed heretofore, and the drag members 1, Q and 3 Will remain in the longitudinally olif-set relations shown in Figure 1 of the drawings.

A means is provided for holding the drag members 1, 2 and 3 at an adjusted lpitch with respect to the surtace which is being dragged. The aforesaid `means includes an extension 17 secured to the intermediate upstanding post 8, aud forming part thereof, the extension 17 being made up of a pair of parallel bars 18 that are held rigidly at a fixed distance apart by connecting` bolts 19er the like, A nut 2O is located between the bars 17 and has trunnions 21 mounted to turn in the lbars 18, so that the nut Q0 may be said to be pivotally mounted en the second post 8-17. An inclined screw 22 is threadedinto the nut 20 and is provided at its rear end With a handle 23 for the ready turning of the screw at the hand of an operator. The lower forward, end of the 'screw 22 has a swveled connection 'with the 'intermediate tis' bar 115 T swiveled connection may be brought about by journaling the screw 22 in a yoke 24, the screw having a head 25 that bears against the inner side or' the end of the yoke 24, the yoke being piyoted at 26 to the intermediate tie bar 1l. It is clear that by threading the screw 22 lengthwise through the nut 20, the tie bar l1 will be moved longitudinally, thereby tilting the posts 7 and 8 and changing the inclination ci" the blades 5 with respect to the surface ot the roadway.

That is claimed is y l. A machine of the class described, comprising rear, intermediate and front drag members having their ends arranged in approximately parallel. lines that are acutely disposed with respect to the dra't't line, upstanding lirst posts secured to the ends of the drag members, upstanding second posts secured to the drag members, the second post ot the intermediate drag member being located midway between the ends ot' the intermediate drag member, and thc second posts of the `lront and rear drag members being so located on the trent and rear diag` members as to define a long part and a short part in the front and rear drag members, the long parts of the front and rear drag members being located at diagonally opposite corners ot the machine,

outer tie bars pivotcd to the first posts and following approximately said acutely disposed lines, an intermediate tie bar disposed at right angles to the drag' members and pivoted to the second posts, )fi-shaped braces comprising arms pivoted to the intermediate and to the front and rear drag members, the arms of each brace that are piVoted to the short parts of the front and rear drag members being spaced apart less Widely than are the arms ot each brace that are pivoted to the long partsof the front and rear drag members, and means for holding the drag members at an adjusted pitch with the surface which is being dragged.

2. A machine of the class described, comprising rear, intermediate and front drag members having their ends arranged in approximately parallel lines that are acutely disposed with respect to the draft line, upstanding first posts secured to the ends of the' drag members, upstanding second posts secured to the drag members, the second post of the intermediate drag member beine' located midway between the ends of the second drag` member, and the second posts of the front and rear drag members being so located on the front and rear drag members to define a long part and a short part in the front and rear drag` members, the long parts of the front and rear dragr members being located at diagonally opposite corners of the machine, outer tie barspivoted to the first posts and foltowing approximately said acutely disposed lines, an intermediate tie bar disposed at rightvangles to the drag members and pivoted to the second posts, X-shaped braces'pivoted at their inner ends to the intermediate member and at their outer ends to the front and rear members, a nut pirotally mounted in the second post of the intermediate drag member, and a screw threaded into the nut and having swivel connection with the intermediate tie bar.

ln testimony that I claim the foregoing as my own, I have hereto aiiixed my signature.
